Thanks Ross, Laurie,Dave and Hugh for your comments on the colour, this was the first test of the Hb filter. I thought the colour would be mapped a little more realistic than using S2.

Nice, it is a great object, that is very dim. You have done it justice.

Great rendition, Ken! I wouldn't have thought to use Hb, but the filter mapping as blue appears to have lifted the image very well. You must have toned down the OIII mapped as green or made the OIII near cyan, similar to the Hb emission line. How much nebulosity is present in the Hb master alone as this is really a strong OIII target? Well done.

[Ken]

Thanks Paul and Jason yes the O3 was stronger than Hb and having twice as many O3 subs meant I had to stretch the blue a bit more. The sky background is still fairly neutral in colour balance though.

Now that's very very nice, and the colours are superb. Very soothing to look at. Great work Ken, thanks for the view!

Thanks Rolf glad you like it.
